(1)
The MASTER/SLAVE bit (SPICTL.2) is set and the CLOCK PHASE bit (SPICTL.3) is set.
(2)
tc(SPC) = SPI clock cycle time = LSPCLK/4 or LSPCLK/(SPIBRR + 1)
(3)
Internal clock prescalers must be adjusted such that the SPI clock speed is limited to the following SPI clock rate:
Master mode transmit 25-MHz MAX, master mode receive 12.5 MHz MAX
Slave mode transmit 12.5-MHz MAX, slave mode receive 12.5 MHz MAX.
(4)
tc(LCO) = LSPCLK cycle time
(5)
The active edge of the SPICLK signal referenced is controlled by the CLOCK POLARITY bit (SPICCR.6).
